"Clinical data have shown a significant reduction in the incidence of ER+ breast cancer in postmenopausal women with osteoporosis who were treated with lasofoxifene," said Paul Plourde, MD, Sermonix vice president of clinical development. "Additional non-clinical and clinical study results provide further impetus for undertaking a Phase 2 trial in a targeted way that compares lasofoxifene to fulvestrant, a current, widely used injectable medication for advanced metastatic breast cancer."

Linical Accelovance Group, a mid-size global contract research organization, will serve as Sermonix’s research partner for the study, enrolling 100 patients in 27 sites across the U.S.

"Sermonix selected Linical Accelovance to be our clinical research development partner for this program because we are impressed with the organization’s integrated clinical trial services, as well as its operational capabilities in the development of oncology drugs," said Sermonix Chief Operating Officer Dr. Miriam Portman.

The trial will utilize oral lasofoxifene for advanced breast cancer patients with ESR1 gene mutations. The primary clinical endpoint will be progression-free survival (PFS).

"Sermonix is developing lasofoxifene as a personalized medicine treatment for patients with ER+ metastatic breast cancer that have progressed after endocrine and other therapies," said Sermonix Chief Executive Officer Dr. David Portman. "We look forward to seeing how it performs in the Phase 2 trial versus fulvestrant."

About Lasofoxifene

Lasofoxifene is an investigational, nonsteroidal selective estrogen receptor modulator (SERM), which Sermonix licensed from Ligand Pharmaceuticals Inc. (NASDAQ: LGND). Lasofoxifene has been studied in comprehensive non-oncology clinical trials recruiting more than 15,000 women worldwide and has demonstrated efficacy for treating vulvovaginal atrophy (VVA), and postmenopausal osteoporosis.

Oral Lasofoxifene’s binding affinity and activity in mutations of the estrogen receptor may hold promise for patients who have acquired resistance and mutations of the estrogen receptor, a common mutation in the metastatic setting and an area of high unmet medical need. Lasofoxifene’s novel activity in ESR1 mutations has recently been discovered and Sermonix has exclusive rights to develop and commercialize oral lasofoxifene in this area. Oral Lasofoxifene, a potent, well-tolerated and bioavailable SERM, if approved could play a critical role in the personalized treatment of advanced ER+ breast cancer.

Celltrion and Teva Announce FDA Oncologic Drugs Advisory Committee Recommends Approval of Celltrion BLA for CT-P10, a Proposed Rituximab Biosimilar

On October 10, 2018 Celltrion, Inc. (KRX:068270) and Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA) reported the U.S. Food and Drug Administration (FDA) Oncologic Drugs Advisory Committee voted unanimously 16-0 to recommend approval of CT-P10, a proposed monoclonal antibody (mAb) biosimilar to Rituxan1 (rituximab) for the treatment of adult patients in three proposed indications (Press release, Celltrion, OCT 10, 2018, View Source [SID1234529850]).

The FDA will take the Committee’s recommendation into consideration before taking action on the Biologics License Application (BLA) for the proposed Rituxan biosimilar.

The Committee based its recommendation on a review of a comprehensive data package inclusive of foundational analytical biosimilarity data, nonclinical data, clinical pharmacology, immunogenicity and clinical efficacy and safety data. The results of the clinical development program for CT-P10 demonstrated that there were no clinically meaningful differences between CT-P10 and Rituxan in terms of the safety, purity and potency of the product for the three proposed indications.

"We welcome the Oncologic Drugs Advisory Committee’s recommendation. If approved by the FDA, CT-P10, a proposed biosimilar to Rituxan, will be the first rituximab biosimilar to be approved in the United States for the three proposed indications," said Woosung Kee, Chief Executive Officer of Celltrion. "The development of biosimilars is of great importance in the field of oncology, and has the potential to increase accessibility to therapies for patients."

"If approved, Teva is well positioned to successfully commercialize CT-P10, given our unique portfolio of branded and generic medications, as well as patient support experience," said Brendan O’Grady, Executive Vice President and Head of North America Commercial at Teva. "We are encouraged by the outcome of today’s meeting, which emphasizes the growing importance of biosimilars and the potential value to be introduced into our health systems."

Celltrion and Teva Pharmaceutical Industries Ltd. entered into an exclusive partnership in October 2016 to commercialize CT-P10 in the U.S. and Canada.

1 Rituxan is a registered trademark of Biogen and Genentech USA, Inc.

"VIDAZA became commercially available in China in February and is the only approved hypomethylating agent shown to prolong survival for patients with MDS. With this national reimbursement coverage, we expect more patients to have an opportunity to benefit from VIDAZA in China," commented Dr. Xiaobin Wu, General Manager of China and President of BeiGene, Ltd. "BeiGene is committed to improving patient access to high-quality, innovative cancer treatments."

VIDAZA is recommended by National Comprehensive Cancer Network (NCCN) Guidelines in the US as a front-line treatment. In a global Phase 3 trial (AZA-001) involving intermediate-2 and high-risk MDS patients, VIDAZA significantly prolonged the median overall survival to 24.5 months compared with 15 months for the conventional care regimens (CCR- best supportive care, low-dose cytarabine or intensive chemotherapy) group. In the VIDAZA group, 45% of patients who were dependent on red blood cell transfusions at baseline became transfusion independent compared with 11% in the CCR group.There was a higher objective response rate among patients treated with VIDAZA (49%) as compared to the CCR arm (29%). VIDAZA also delayed the onset of AML for these patients (17.8 months vs.11.5 months). The most common grade 3-4 events were peripheral blood cytopenias for all treatments.

"We are pleased that patients in China will have improved access to VIDAZA and other cancer treatments listed on the 2018 NRDL," said Professor Wang Jianxiang, Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences. "VIDAZA is an important treatment for MDS with demonstrated survival benefit. The broadening access to new treatments like VIDAZA could significantly improve the care of our patients."

About Myelodysplastic Syndrome, Acute Myeloid Leukemia and Chronic Myelomonocyte Leukemia

MDS is a group of conditions that can occur when the bloodforming cells in the bone marrow become abnormal. This leads to low numbers of one or more types of blood cells. In about one-third of patients with MDS, the disease can progress to a rapidly growing cancer of bone marrow cells called AML.i CMML is a type of cancer that starts in blood-forming cells of the bone marrow and invades the blood; it affects mainly older adults. CMML has features of both MDS and myeloproliferative disorder and is considered the most common disease among myelodysplastic/myeloproliferative diseases.ii

About VIDAZA (Azacitidine for Injection)

VIDAZA is a nucleoside metabolic inhibitor indicated in China for the treatment of patients with intermediate-2 / high-risk MDS, AML with 20-30% bone marrow blasts and CMML. It is marketed in China by BeiGene under an exclusive license from Celgene Corporation.

In the US, VIDAZA is indicated for the treatment of patients with the following FAB MDS subtypes: refractory anemia (RA) or refractory anemia with ringed sideroblasts (RARS) (if accompanied by neutropenia or thrombocytopenia or requiring transfusions), refractory anemia with excess blasts (RAEB), refractory anemia with excess blasts in transformation (RAEB-T), and CMML.

Important Safety Information

VIDAZA is contraindicated in patients with a known hypersensitivity to azacitidine or mannitol and in patients with advanced malignant hepatic tumors.

In Study 1 (a randomized, open-label, controlled trial carried out in 53 U.S. sites compared the safety and efficacy of subcutaneous VIDAZA plus supportive care with supportive care alone ("observation") in patients with any of the five FAB subtypes of myelodysplastic syndromes (MDS)) and Study 2 (a multi-center, open-label, single-arm study of 72 patients with RAEB, RAEB-T, CMMoL, or AML), most frequently observed adverse reactions occurring in at least 5% of patients by SC route were nausea (70.5%), anemia (69.5%), thrombocytopenia (65.5%), vomiting (54.1%), pyrexia (51.8%), leukopenia (48.2%), diarrhea (36.4%), injection site erythema (35.0%), constipation (33.6%), neutropenia (32.3%), and ecchymosis (30.5%). Other adverse reactions included dizziness (18.6%), chest pain (16.4%), febrile neutropenia (16.4%), myalgia (15.9%), injection site reaction (13.6%), and malaise (10.9%). In Study 3, the most common adverse reactions by IV route also included petechiae (45.8%), weakness (35.4%), rigors (35.4%), and hypokalemia (31.3%).

In Study 4 (the AZA-001 survival trial, an international, multicenter, open-label, randomized trial in MDS patients with RAEB, RAEB-T or modified CMMoL according to FAB classification and Intermediate-2 and High risk according to IPSS classification), most frequently observed adverse reactions occurring in at least 5% of patients were thrombocytopenia (69.7%), neutropenia (65.7%), anemia (51.4%), constipation (50.3%), nausea (48.0%), injection site erythema (42.9%), and pyrexia (30.3%). The most frequently observed adverse reactions in the percentage with NCI CTC Grade 3/4 reactions were neutropenia (61.1%), thrombocytopenia (58.3%), leukopenia (14.9%), anemia (13.7%), and febrile neutropenia (12.6%).

Because treatment with VIDAZA is associated with anemia, neutropenia and thrombocytopenia, complete blood counts should be performed as needed to monitor response and/or toxicity, but at a minimum, prior to each dosing cycle.

Because azacitidine is potentially hepatotoxic in patients with severe preexisting hepatic impairment, caution is needed in patients with liver disease. In addition, azacitidine and its metabolites are substantially excreted by the kidneys and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, it may be useful to monitor renal function.

VIDAZA may cause fetal harm when administered to a pregnant woman. Females of reproductive potential should be advised to avoid pregnancy during treatment with VIDAZA. Males with female sexual partners of reproductive potential should not father a child and should use effective contraception during treatment with VIDAZA.

The importance of the drug to the mother should be taken into consideration before the breastfeeding mothers decide to discontinue breastfeeding or the drug.
